# update_tool Update a recipe tool's name. Agent View of the PolicyLayer registry record for `update_tool`. HTML page: https://policylayer.com/tools/graysoncadams-mealie-mcp/update-tool ## Facts - Tool: `update_tool` - Server: Mealie MCP Server (`graysoncadams/mealie-mcp`) — https://policylayer.com/tools/graysoncadams-mealie-mcp.md - Homepage: https://github.com/GraysonCAdams/mealie-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "update_tool", "arguments": {} } } ``` ## Why update_tool is rated Medium The tool creates or modifies data reversibly without deleting or executing external code. Severity is medium because renaming a recipe tool has limited blast radius—it affects metadata only and is easily reversible, but could cause confusion if an agent renames tools maliciously or inappropriately. Confidence is high given the explicit 'update' verb and clear modification intent in the description. From the tool's own definition: "Tool description states 'Update a recipe tool's name' — this modifies existing data (the tool's name) in a reversible manner. The verb 'update' and the action of changing metadata (name) are characteristic of Write-category operations." ## Use case AI agents use update_tool to create or update resources in Mealie MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mealie MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
